I ELECTRIC-LIGHT-BULB SHADE.

Specification of Letters Patent.

Patented June 6, 1911.

Application filed March 14, 1911. Serial No. 614,365

To (LZZ whom it may concern:

le it known that I, BENJAMIN R. IVN.- Lmil's, a citizen of the l'nitedStates, residing at lilnglisli. in the county otl Jefferson and\State otArkansas. have invented cer tain new and useful Improvements inElectric-Light-Bulb Shades, ot which the following is a specification. i

My invention has relation to electric-- light bulb shades aiuljtmsistsVin a shade of two parts adapted to be adjustably and removably securedto the electric light bulb socket,

and to be shifted from side to side on the saine. The bulb may be round,oval shaped, or any other appropriate shape but the shades arepreferably oval shaped being somewhat larger at their lower ends than attheir upper ends.

The shades are tor the purpose of shading the light and may be of anycolor or density, but they may be opaque. The shades are so constructedthat'one only may be used at a shade and the outer shade in section.

time, or both may be used conjointly at the same time. The: shades arealso so constructed that one or both may be removed or one may beslipped around so as to cover the opening of the other. Y

In the accompanying drawings: Figure 1 is an elevation of an electriclight socket, the shade holder and .bulb with my shades attached. Fig. 2isL-ja view similar to Fig. 1 with 'a part of the device broken awayshowing apart of the shade holder of theIiwnner 1ig. 3 is a perspectiveview of the innershade. Fig. t is a perspective view of theouter shade.y

My invention is described as follows: The inner shade 1 is provided withan extended open neck 2 and a closed oval bottom 3 and is provided atone side and near its center with an opening 4, substantiallyrectangular 'nearly one-third of its entire length and 1n width aboutone-fourth of the entire ci rcumference of' the shade.- The neck of'said shade is provided with a circular depression 5 terminating at itsupper end with a flange 6 and below the depression with a shoulder 7.The,- socket 8 is the usual ,commercial socket and is provided with ashade holder 9 provided with the usual lower extensions 10 and threadedscrews 11 which screws pass through said extensions and abut against theneck 6 of the inner shade and contact it at the center of the depression5 whereby the inner shade is held rotatably in place. The outer shade 12isv also oval shaped except that it is open at its bottom end. It islarger than the inner shade so that it ma be easily revolved around thesame. t gradually however, narrows at its upper end leaving an opening13 and the inner surface of its upper end is provided withan innervinwardly extending lenlargement 14, said opening 13 is large enough toallow the neck 6 of the innerv shade to pass through it but is soconstructed that the enlargement 14 will rest lsnugly against theshoulder 7 of the inner shade 1 and thereby keep it from slipping 'oft'.The two shades are of such size, the one kin relation to the other thatthe inner shade when released from the shade holder, may be drawn downthrough/the bottom and, entirely out of the outer shade. As the innershade is closed at its bottom, its bottom part answers as a bottom tothe outer shade when they are both hung at the same time. The outershade is also provided in its side with an opening 15, the same shapeand size as the opening 4 in shade 1.

In attaching my shades to the shade holder 93 I first slip the innershade up into the outer shade until its neck 2 passes up throughtheopening 13 in theouter shade and until its flange (i abuts againstthe lower face ot the iange holder 9. I then insert the screws 11turning them until their inner ends come in contact with the depression5 of the neck 2. Then I let the outer shade 12 down until the innerenlargement 1.1L rests on the shoulder 7 of the inner shade'. The flange6 so neatly fits in the'shade holder 9 that no light can pass up betweenthe two. It will be seen that when the two openings fl and 15 arebrought concentric with each other a volume of light from the bulb canpass out through these openings, lighting up only a certain section oftheroom. or in caseethis light should be used tor purposes to light upastreet or other purposes outside oil a room it would throw a stream oflight equal to the size of the openings considering the angle trom thebulb wire. By `turning the outer shade 12 I can gradually diminish therays of light until it is very small or rIcan further turn the shade andturn the light entirely oil". It will readily beseen how important thisinvention is, especially in rooms when there are persons who are'sick,nervous or having weak eyes. Such persons may be in one part of the roomwhile the other occupant or occupants may light up the other part tosuch extent as may be desirable and thus they may be able to read orattend to business While the other party or parties-may be undisturbed.

It will be observed that the inner shade is rotatably secured in theshade holder and in ease Where the neck is permanently secured to theelectric Wire or other device holding it so that it may not be revolved,my shade may be so secured t'o said'shade holder that the light may beturned in any direction.

Having described my invention what I claim as new and desire to secureby Letters Patent, is:

l. The combination with an electric light socket and shade holder, anoval shaped bulb, closed at its bottom and having an open neck 2, saidneck having an .outwardlyY extending flange (3, a depression 5, saidbulb also provided immediately below said depression 5 with a shoulderl0 iand in.the body of said shade an opening Ll, an outer shade l2opened at its bottom end andhaving an opening at its upper end largeenough for said neck and flange to pass through` said shade provided onits inner surface with an enlargementI 14, adapted to lit against theshoulder 7 of said inner shade, said shade provided With an opening l5the saine size vand shape of the opening 4 in shade 1, substantially asshown and described.

2. In combination With a light socket and shade holder, an oval shapedshade adapted to surround the light and lhaving in its side an opening:rand provided with a neck adapted to be secured in said shade holder withmeans to so secure said shade, an outer shade adapted to surround saidinner shade and provided at its upper end with an inner enlargementadapted to rest on the shoulder of said inner shade, said outer shadepron vided with an opening substantially the same size and shape of theopening orn the inner shade.

3. In combination with a shade holder, an oval shaped inner shadeadapted to be rotatably and removably secured to said shade holder, andprovided with a shoulder near its upper end and an opening in its side,an outer shade adapted to encircle said inner shade and provided at itsupper end with an enlargement vto rest on the shoulder of said innershade, said outer shade provided with an opening substantially the sameshape and size of the opening' in the inner shade, substantially asshown and-deseribed- In testimony whereof I ailix my signature inpresence of two witnesses.
